Aball is on the end of a rope that is 1.72 m in length. the ball and rope are attached to a pole and the entire apparatus, including the pole, rotates about the pole's symmetry axis. the rope makes an angle of 64.0° with respect to the vertical. what is the tangential speed of the ball

Tangential Speed equals 5.57m/s

Explanation:

In the figure shown for equilibrium along y- axis we have

Resolving Forces along y axis we have

Similarly along x axis

............(ii)" alt="\frac{v^{2} }{r}" />............(ii)" />

Dividing ii by i we have

In the figure below we have

Thus solving for v we have

Applying values we get

v=5.576m/s

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
